turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)
